spark ignition

基本解釋

Two methods for igniting fuel are used, spark ignition and compression ignition.
按點(diǎn)火方式可分為兩種：火花點(diǎn)火和壓縮點(diǎn)火。
The two major engine types in use are spark ignition (gasoline engine) and compression ignition (diesel engine) which use different types of fuel.
常用的兩大類內(nèi)燃機(jī)是火花點(diǎn)火式（汽油機(jī)）和壓縮點(diǎn)火式（柴油機(jī)）內(nèi)燃機(jī)，他們使用不同種類的燃料。
In the near future, spark ignition engines have rapid progress depending on their high efficiency and low pollution for the requirement of energy source and environmentalism.
近年來，由于能源和環(huán)保的要求，火花點(diǎn)火天然氣發(fā)動(dòng)機(jī)以高效、低污染燃燒的優(yōu)點(diǎn)正在迅速發(fā)展。

In most spark ignition engines, a thermodynamic cycle occurs when the piston completes four strokes within the cylinder, and the crankshaft completes two revolutions.
FORBES: How To Get 50 MPG Out Of Your Gasoline Engine
Both Otto cycle(spark ignition) and Diesel cycle engines(compression ignition) engines can be made to run on multiple fuels(petroleum, ethanol, natural gas) The cost is only nominally more than single fuel engines.
FORBES: The U.S. Federal Deficit Reaches A Tipping Point
Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.

火花點(diǎn)火
The data structure of visualization model is given and a temperature-color mapping table is created. By using the combustion visualization model, the 3D dynamic visualization for both spark ignition engine and compression ignition dual fuel engine are realized.
